SF Protects I-80 Bridge with Maintenance Work

Eastbound I-80's 4th Street off-ramp closed for bridge work, drivers detoured to 7th Street

I-80 Off-Ramp Closure

Drivers heading into San Francisco on eastbound Interstate 80 face a detour as the 4th Street off-ramp remains closed for bridge work. Transit officials said the closure affects commuters and travelers in the San Francisco-San Jose metro area, though a specific reopening date wasn't provided. Motorists must use the 7th Street exit instead to reach local streets.

Detour Route and Impact

The closure forces drivers who typically use the 4th Street exit to continue to the 7th Street off-ramp, adding distance to trips into the city. Officials said the work is necessary for bridge maintenance, though specific details about the project scope and timeline weren't available by publication time. Transportation agencies typically close ramps for bridge work when repairs can't be completed safely with traffic present. The 4th Street off-ramp serves as a key access point for downtown San Francisco and surrounding neighborhoods.

Traffic Disruption Details

The closure affects one of the main entry points from eastbound I-80 into San Francisco, though officials haven't released data on how many vehicles typically use the ramp daily. Drivers unfamiliar with the area may experience confusion when encountering the closed ramp, potentially leading to missed exits or unsafe lane changes. The 7th Street detour adds approximately three to four blocks of additional travel for those heading to destinations near 4th Street. Officials haven't said whether additional signage or traffic control measures have been implemented to guide drivers to the alternate route.

Project Timeline Unknown

Officials confirmed the closure remains in effect as of late February 2026, but haven't announced when the ramp will reopen. Transportation agencies typically provide estimated completion dates for major closures, though that information wasn't available. The duration of bridge work projects can vary significantly depending on the extent of repairs needed and weather conditions.

Planning Your Route

Commuters who regularly use the 4th Street off-ramp should allow extra travel time and plan to exit at 7th Street until the closure ends. Officials recommend familiarizing yourself with the detour route before your trip to avoid last-minute lane changes.
